I sent this earlier but I don’t think it ever came through. Sorry if  
this is a reposting.

When using :priority\_zones for time\_zone\_select in a manner described  
by the API docs for ActionView::Helpers::FormOptionsHelper I’m getting  
errors.  
Here is an API docs example:  
time\_zone\_select( “user”, ‘time\_zone’, TimeZone.us\_zones, :default =\>  
“Pacific Time (US & Canada)”)

When using this code I get “uninitialized constant  
ActionView::CompiledTemplates::TimeZone”.

The first thing I noticed was that TimeZone is camel cased. This seems  
confusing to me considering TZInfo::Timezone is proper cased. I tried  
using proper cased Timezone and continued to get the same error. Next,  
I tried using TZInfo::Timezone, this worked.

time\_zone\_select( “user”, ‘time\_zone’,  
TZInfo::Timezone.us\_zones, :default =\> “Pacific Time (US & Canada)”)

It seems that I’m either doing it wrong, there is a different way to  
do it in Rails 3.0, the documentation is wrong, or there is a bug  
(understandable since I’m using Rails 3.0 beta).

Can anybody shed light on this?

The documentation might be outdated. Here’s a ticket I found. It  
possibly  
never got updated.
